5 Claims.

My invention relates to a novel and improved cotton or hay press andrebander and has especial reference to one which is portable so that itcan be readily moved in a truck from one warehouse to another.

The invention also contemplates a device of this kind which is simpleand durable in construction, easy to operate, and which includes a novelcable incorporating actuating means comprehending a floatingcable-supported guide frame and means actuated by the cable for ef-.fecting actuation of the press.

Additionally, the invention contemplates a press for cotton or othermaterial which incorporates a "cable-operated toggle actuating means.

Other objects and advantages will become apparent as the descriptionproceeds, reference being had to the accompanying drawings illustratinga now preferred example of the invention, which, however, may beconsiderably changed and modified within the spirit and scope of theappended claims.

In the drawings,

Figure 1 is a side elevation of a press embodying my invention.

Figure 2 is a sectional view taken on line 22 of Fig. 1 of the presswithout the bale.

Figure 3 is an end elevational view, and

Figure 4 is a central vertical sectional view.

Referring specially to the drawings, wherein the same referencecharacters have been used to designate the same parts in all views,letter A designates .a platform or base member supported by wheels B.Mounted upon platform A is an upstanding fixed frame comprehendingpreferably angle iron corner posts 5, top cross members 5a, 5b, thebrace members 50 extending from posts 5 for reinforcing the medialportions of top cross 5a. which carry the bearings I for the shaft 8 ofthe pulleys 9. The fixed frame also has the side bars 5d connecting theposts 5 intermediate their ends, as shown in Fig. 1. Furthermore, asshown in Figure 4, the inner ends of the bearings 1 are supported by thevertical posts I carried by the cross member I 0b extending betweenintermediate side bars d, as shown in dotted lines in Fig. 1. Posts Ii]also have the vertical slots Illa, as shown, the purpose of which willbe shortly explained.

Working within the fixed frame and guided by the angle iron corner posts5 thereof, as best shown in Fig. 2, is a slidable frame comprehendingthe upstanding preferably angle iron corner posts 6, upper and lowerside members 6b and 6a., respectively, and the intermediate bars 50connecting corner posts 6.

The slidable frame also has the vertical slat members I8 connectingmembers 6b, 60 at each side; and also the swingable gate-like slatmembers I6 pivotally carried as at IBa. by intermediate bars 60 andadapted to be secured by pins I? 'in -slots IS-a "in the outer ends ofthe preferably channel-form compressor head cross bars which aredisposed across the lower side members 5a, as best shown in Figures 1and 2.

It should here be noted that the fixed frame 5, 511, etc. has the shortchannel form compressor 'head cross bars I4 connecting the intermediate'si'de bars 5d, as shown in Figs. 1, 3, and 4. The space between thebars I4, I5 of the fixed and movable frames, respectively, is the balechamber and the "bale, such as 25 therein, is adapted to be compressedby the upward actuation of the sliding frame 6, 60., etc., which causesthe compressor head bars I5 to compress the bale against the compressorhead bars I4.

The means whereby the sliding frame 6, 5a, etc. is actuated will now bedescribed.

Figures 1, 3, and 4idisc1ose the vertical bars II depending from themedial portion of each upper side member 6b of the movable frame 6, 6a,etc.; and also that the lower ends of such vertical bars I'I carry theshaft I2 having the spaced pulleys I3. Figures 3 and lshow that the endportions of shaft I2 extend through the slots Illa in "the verticalposts Ill of the fixed frame 5, 5a, etc., to

be thereby guided and sustained in the vertical,

movements of slidable frame 6,611,, etc.

Toggles'comprisin'g side arms I9, I9, and 20, 20, connected byreinforcing frames I9a, a (Figs 3 and 4) are arranged in pairs I9, 20and I9, 20, as shown with their inner ends connected by shafts 23, 23arespectively, having the laterally spaced pulleys 24, 24a, respectively.The outer ends of arms I9 are pivotally connected to the upper sidemembers -6b of the slidable frame, as shown at 22 in Figure "1'; and theouter ends of the arms 20 are pivotally secured as at 21 to theintermediate side "bars 5d of the fixed frame. Thus, when thepulley-carrying shafts 23, 23a which connect the pairs of arms I9, 20and I9, 20 are actuated inwardly, the pivot points 22, 2| (Fig. 1') tendto separate with the result that sliding frame 6, "6a, etc. will beactuated upwardly to compress the bale of hay, cotton, or the like 25between the 'heads provided -by the channelform cross bars I I, I5.

In order to actuate the pivots 23, 23a inwardly toward one another asaforesaid, I provide the cable 29 having one end wound on the drum 21which is secured on base A and has the geared or other drivingconnection 28'with the motor 26, which is also secured to the base A.

Cable :29 passes from drum 21 over pulley 30 whose shaft 38a 'is carriedby bearings 3I intermediate the ends of the corner posts 5 of the fixedframe5, 5a, etc.

From pulley 30 cable 29 divides into two branches which pass under therespective pulleys I3 of the depending bars I I of the movable frame andwhich pulleys I3 have their shaft I2 guided in slot Illa of posts I0, asalready mentioned.

After passing around the lower parts of pulleys I3, the branches ofcable 29 lead upwardly (Figs. 1 and 4) about the inner portions of thelaterally spaced pulleys 33 of a floating frame 32 which is entirelysupported by the branches of cable 29, as will be presently apparent.

The branches of cable 29 pass over the pulleys 33 and outwardly to thespaced pulleys 24 of the toggle arms I9, 28 at the right (Fig. 1)passing about said pulleys 24 and then back and under the spacedcompanion pulleys 34 of said floating cable-supported frame 32. Fromthence the cable branches lead upwardly and over the spaced pulleys 9carried by the members 5a, I0, I, 8 of the fixed frame 5, 5a, etc., asshown in Figs. 1, 3, and 4.

From pulleys 9, the branches of cable 29 pass downwardly and under theupper pulleys 35 of the floating frame 32. From pulleys 35 cablebranches 29 pass outwardly to be trained about the spaced pulleys 24a ofthe left hand toggle arms is, 20 (Fig. 1) whence they are broughtinwardly to floating frame 32 which provides the spaced pulleys 36 overwhich said branches of cable 29 are trained and finally lead downwardlyand are appropriately secured to the floating frame.

The operation may be briefly summarized as follows:-

The bale 25 to be compressed having been inserted into the bale chamberspace between the compressing heads I4, I5, the gate bars I6 are letdown and locked in place by pins II, whereupon the motor 26 is startedcausing cable 29 to be wound onto drum 21. This causes the intermediatetoggle pivots 23, 23a to be pulled toward one another. Since the outerends of toggle arms 26 are pivoted to 5d which is a part of fixed frame5, 511, etc., the sliding frame 6, 6a, etc. will be lifted and the bale25 compressed between the head I 4, I5 of the fixed and movable framesrespectively. The pull of the cable on pulleys 9 is is amply sustainedby 5a, 50, 5 and by posts II]; and the slot Illa of post In sustains theshaft I2 of pulleys I3 (Figs. 1 and 4) which, of course slides up anddown with frame 5, 511, etc.

By making the compressor head cross bars I4, I5 of channel form thepassing of bale wires under and over the bale 25 is greatly facilitatedas such bars guide the wires.
